Question
Can you answer all the parts to this question please
In shoot apical meristems, the peripheral zone (PZ) genetic program maintains indeterminacy and allows lateral primordia initiation.
(a) Explain how the PZ genetic program control (1) meristem maintenance, (2) organ separation, and (3) organ differentiation/leaf primordia outgrowth using the following keywords: KNOX genes, cytokinins, gibberellin, auxin, CUC, and AS1.
(b) Explain how this genetic program is used in the formation of compound leaves.
(c) Please use KNOX PZ genetic module as an example to explain process homology during compound leaf evolution.
